‘Rainbow’ was released last year after Kesha’s long legal battle with Dr. Luke ended, and is the first album the singer has released in five years.

The producer was accused of sexual abuse, harassment and inflicting emotional distress on the singer in 2014.

The legal proceedings lasted for three years before being dismissed by Judge Kornreich.

“Making‘Rainbow’ the album was such a therapeutic process and given the opportunity to turn it into a three-dimensional piece of art has helped me find even deeper healing and catharsis,” Kesha said in a statement.
